Pangonia unicolor Macquart, Dipt. Exot. Suppl. 1, 55, pi. iii, f . G.— Brazil. 

 Numerous specimens. The antennae are slender, the third joint 

 but little expanded at the base, the second to the seventh annuli of 

 the third joint of nearly equal length, the eighth as long as the three 

 preceding together. The face is conically produced. The second 

 joint of the palpi is as long as the third joint of the antennae, and is 

 slenderly crescentic in shape. A rudiment of a vein is present on the 

 anterior branch of the third vein, but the first posterior cell is open. 

 The proboscis is long, and the labium is coiled up within the buccal 

 cavity, admitting of great extension. 



Pangonia pyrausta Osten Sacken. Biul. Centr. Amer. Dipt, i, 43.- Mexico. 

 A single female specimen from Mexico agrees in all respects with 

 the description of this species, save in the absence of the mesonotal 

 stripe and the white hair of the abdomen, and in the third joint of 

 antennae being ferruginous.
